== Function ==
[https://www.uniprot.org/uniprot/SH2B2_RAT SH2B2_RAT] Adapter protein for several members of the tyrosine kinase receptor family. Involved in multiple signaling pathways. Binds to EPOR and suppresses EPO-induced STAT5 activation, possibly through a masking effect on STAT5 docking sites in EPOR. Suppresses PDGF-induced mitogenesis (By similarity). Involved in stimulation of glucose uptake by insulin. Involved in coupling from immunoreceptor to Ras signaling. Acts as a negative regulator of cytokine signaling in collaboration with CBL. Induces cytoskeletal reorganization and neurite outgrowth in cultured neurons.<ref>PMID:9856458</ref> <ref>PMID:10854852</ref> <ref>PMID:11997497</ref> <ref>PMID:15031295</ref>

== Publication Abstract from PubMed ==
The adaptor protein APS is a substrate of the insulin receptor and couples receptor activation with phosphorylation of Cbl to facilitate glucose uptake. The interaction with the activated insulin receptor is mediated by the Src homology 2 (SH2) domain of APS. Here, we present the crystal structure of the APS SH2 domain in complex with the phosphorylated tyrosine kinase domain of the insulin receptor. The structure reveals a novel dimeric configuration of the APS SH2 domain, wherein the C-terminal half of each protomer is structurally divergent from conventional, monomeric SH2 domains. The APS SH2 dimer engages two kinase molecules, with pTyr-1158 of the kinase activation loop bound in the canonical phosphotyrosine binding pocket of the SH2 domain and a second phosphotyrosine, pTyr-1162, coordinated by two lysine residues in beta strand D. This structure provides a molecular visualization of one of the initial downstream recruitment events following insulin activation of its dimeric receptor.
